以下是渐变的js代码(表示多余三行的要隐藏，点击"more"显示剩下的，点击“less”要逐渐隐藏)：

function showAccomplishmentTableRow(){
$("#accomplishmenttable tr:hidden").first().show(2000,function(){
showAccomplishmentTableRow();
});
if($("#accomplishmenttable tr:hidden").size()==0){
$("#accomplishmenttable").next().attr("onclick","hideAccomplishmentTableRow()").text("Less");
}
}
function hideAccomplishmentTableRow(){
if($("#accomplishmenttable tr:visible").size()<=3){
$("#accomplishmenttable").next().attr("onclick","showAccomplishmentTableRow()").text("More");
return;
}

$("#accomplishmenttable tr:visible").last().hide(2000,function(){
hideAccomplishmentTableRow();
});

}
